Description

  The present invention includes a wrapping container for wrapping wrapping such as sashimi, meat and other ingredients, side dishes, cooked foods and the like, and wrapping the opening with a wrap film. It is related with the food packaging body wrapped and wrapped.

Conventionally, a synthetic resin foam sheet or a non-synthetic resin is used as a wrapping wrapping container in which wrapping materials such as sashimi and meat, side dishes, and cooked foods are put and wrapped with a wrap film. A container obtained by forming a foam sheet into a tray shape or the like is provided.
In this conventional wrapping wrapping container, a general wrapping wrapping container whose upper edge of the opening portion is substantially in the same plane can be obtained by lowering the side wall so that the wrapping can be seen well from the outside. May come into contact with the film. On the other hand, if the side wall is too high, the packaged item becomes difficult to see. Also, the appearance of this container is mediocre, and it has no effect to appeal the product to consumers.

On the other hand, a container in which a part of the container is formed high has been proposed in order to package the packaged article so that it can be seen well from the outside and the wrap film does not come into contact (see, for example, Patent Document 1).
Patent Document 1 discloses a packaging container having a side wall that is inclined while being expanded with respect to a bottom surface having a curved or bent shape, and a part of the side wall is moved upward within a range of the inclination width. A packaging container is disclosed which is bulged to form a support protrusion protruding from the upper side of the side wall so that the support protrusion does not protrude above the bottom surface. In this packaging container, when the wrap film is hung on the opening, the wrap film is stretched in a tent shape by the supporting projections to prevent the packaged item from coming into contact with the wrap film. .

Patent Document 2 discloses a structure in which an arc-shaped convex portion that bulges upward is provided on a short side wall in a container having a substantially rectangular shape in plan view. Also about this patent document 2, when applying a wrap film to an opening part, the wrap of a container center part is raised by the convex part of a short side wall, and the accommodation space can be expanded and it prevents that a packaged item contacts a wrap film. It is like that.
Japanese Utility Model Publication No. 7-8207 Design Registration No. 1137095

  However, in the conventional wrapping and packaging container disclosed in Patent Document 1, when a wrap film is hung on the opening, the packaged object is in contact with the film around the support protrusion that is locally raised. However, no matter how much the wrap film is stretched and applied to the opening, the depression of the film is not eliminated except around the support protrusion. In addition, by providing the support protrusions, the film can be easily wavy or wrinkled. As a result, there is a problem that it is difficult to completely avoid the contact between the package and the film except in the vicinity of the support protrusion, and the package is difficult to see. Furthermore, the conventional wrapping packaging container disclosed in Patent Document 1 has a problem that when a wrapping film is hung on an opening, the film is easily broken if the film is stretched and adjusted forcibly to stretch.

  In addition, the container disclosed in Patent Document 2 is such that when a wrap film is hung on the opening, the central portion of the opening of the wrap film is easily recessed, and the recessed portion is easily in contact with the packaged object. There is a problem that wrinkles are likely to occur.

  The present invention has been made in view of the above circumstances, and is a packaging container for wrapping an opening, and when wrapped, it can be wrapped so that the inside of the wrap film container opening is hardly depressed and no wrinkles enter. An object of the present invention is to provide a wrapping packaging container and a food packaging body in which the contents do not come into contact with the film and the packaged article is easy to see at the time of display.

  In order to achieve the above object, the present invention provides a wrapping wrapping in which a synthetic resin sheet is formed into a container shape including a bottom plate portion and a side wall standing from the periphery thereof, and is wrapped with a wrap film over the opening. A container having a planar shape having a short side and a long side, the upper edge of the long side wall and the upper edge of the short side wall are continuously formed without a step, and the upper edge of the long side wall A wrap-wrapping packaging container is provided, which is provided with a convex portion for preventing wrap dents that bulges upward in a convex curve.

  In the wrapping packaging container of the present invention, it is preferable that the curve formed by the upper edge of the long side wall is arcuate in side view.

  In the wrapping and packaging container of the present invention, the entire circumference of the upper edge of the container opening is on a two-dimensional curved surface obtained by curving the plane upward into a convex line, or the two-dimensional curved surface and a continuous plane. It is preferable that it exists on the surface.

  In the wrapping packaging container of the present invention, it is preferable that the highest positions of the upper edges of the one long side wall and the other long side wall are in positions facing each other.

  In the wrapping packaging container of the present invention, in the planar shape of the container opening, the side walls on the long side and / or the short side may be gently curved outward from the respective ends toward the center. preferable.

  In the wrapping packaging container of the present invention, it is preferable that the upper edge of the short side is substantially linear in a side view.

  In the wrapping packaging container of the present invention, the upper edge of one long side wall is formed higher than the upper edge of the other long side wall, and the opening is inclined toward the other long side wall. It is preferable.

  In the wrapping packaging container according to the present invention, the ratio C (where C = B / A) of the bulging height Bmm of the convex portion for preventing wrap depression to the length Amm of the upper edge of the long side wall is 1 It is preferably within the range of / 7 to 1/100.

  In the wrapping packaging container of the present invention, the ratio D (where D = r / A) of the radius of curvature rmm of the convex portion for preventing wrap depression and the length Amm of the upper edge on the long side wall is 13 to 0. Is preferably in the range of .95.

  In addition, the present invention provides a food packaging body in which a food product to be packaged is placed in the wrapping packaging container according to the present invention, and the wrapping film is hung on the opening of the container.

The wrapping packaging container and food packaging body of the present invention can stretch the wrap film without wrinkles, slackness, or dents at the opening, making it difficult for the packaged article to come into contact with the film and making it easy to see the packaged article at the time of display. Therefore, a clean feeling and a high-class feeling can be improved.
The stretched wrap film follows the upper edge of the opening without difficulty. Therefore, it is possible to wrap without dents or wrinkles by applying a slight extension to the extent that the wrap film is removed, and wrap-wrap packaging is facilitated.
In addition, the inside of the opening of the stretched wrap film is hardly recessed. Therefore, even if the side wall is not made excessively high, there is no fear that the packaged object will come into contact with the film, and the clean feeling and the high-class feeling can be improved.
In the food package of the present invention, the height of the side wall decreases as it goes from the long side wall to the short side wall of the container, and the packaged article can be seen well from the outside. In particular, the upper edge of the front long side wall is formed lower than the upper edge of the rear long side wall, and the opening is inclined toward the front long side wall. The package is easier to see.
In addition, the container of the present invention has a structure in which at least the long side wall is gently curved outward in the planar shape of the opening, so that the side wall is bent to the inside by the stretched wrap film. Because they can face each other, the wrap film is difficult to loosen, and the wrap film can be kept stretched for a long time without being depressed or wrinkled at the time of display, and it looks good, clean and luxurious Can be improved.
In addition, since the wrap film has a convexly curved surface and is in a tensioned state, there is an effect that when a large number of wrap films are arranged and displayed on the sales floor, the surrounding illumination is reflected and the surroundings are felt bright.
Furthermore, if the curved line formed by the upper edge of the long side wall is arcuate in side view, the container can be easily designed, and the appearance of the container can be improved naturally.

Hereinafter, an embodiment of a wrapping packaging container of the present invention will be described with reference to the drawings.
FIG.1 and FIG.2 is a figure which shows 1st Embodiment of the container for wrapping packaging of this invention, Fig.1 (a) is a top view of the container for wrapping packaging, (b) is in (a). BB 'line sectional drawing, (c) is CC' line sectional drawing in (a), FIG. 2 is a perspective view of the wrapping packaging container. In these drawings, reference numeral 1 is a wrapping packaging container, 2 is a bottom plate portion, 3A is a long side wall, 3B is a short side wall, 4 is a dent for preventing wrap depression, 5 is an upper edge of the side wall, 6 Is a hanging portion, 7 is an opening, and 8 is a small protrusion.

  The wrapping packaging container 1 according to the present embodiment is formed by molding a synthetic resin sheet into a container shape including a bottom plate portion 2 and side walls 3A and 3B erected from the periphery of the synthetic resin sheet. A container for wrapping and wrapping, the planar shape of which is substantially rectangular, the upper edge 5 of the long side wall 3A and the upper edge 5 of the short side wall 3B are continuously formed without a step, The edge 5 is provided with a convex portion 4 for preventing a wrap dent that bulges in an upward convex curve that gradually decreases from the center of the upper edge 5 toward both ends.

  Examples of the synthetic resin sheet forming the wrapping packaging container 1 include polyethylene resins, polypropylene resins, polystyrene resins, polyethylene terephthalate resins, thermoplastic resins such as alloys of polystyrene resins and polypropylene resins, or the like. Examples thereof include a foamed sheet of a composition obtained by mixing an inorganic filler such as talc with a resin, or a non-foamed sheet, and a polystyrene-based resin foamed sheet is particularly preferable. The thickness of the synthetic resin sheet is not particularly limited, but is preferably about 0.5 mm to 5 mm in the case of a foamed sheet of thermoplastic resin and about 0.2 mm to 1 mm in the case of a non-foamed sheet. The molding method for producing the wrapping packaging container 1 from the synthetic resin sheet can be performed using a conventionally known sheet molding method.

  The wrapping packaging container 1 of the present embodiment can be used as a container with printing by laminating at least the inner surface side of the container with the printed surface side of the printed synthetic resin film superimposed on the surface of the container body. As this printing method, it can carry out using the various printing methods and printing ink conventionally used for the printing of the container made from a synthetic resin. The pattern or color to be printed is not limited, and patterns, characters, marks, and the like can be displayed in one color or multiple colors.

  In the wrapping packaging container 1 of the present embodiment, the angle formed by the average opening surface of the opening 7 and the side walls 3A and 3B is preferably in the range of 40 to 85 degrees. Here, the “average opening surface” is a virtual plane obtained by connecting the average positions of all the upper edges 5 of the side walls 3A and 3B. If this angle is 85 degrees or less, when the wrap film is put on the opening 7 of the container, a sufficient elastic restoring force can be obtained even if the side walls 3A, 3B are bent to the inside of the container by the tension of the wrap film. As a result, it becomes easy to maintain the tension of the wrap film. If this angle is smaller than 40 degrees, the side walls 3A and 3B are inclined to the outside too much, so that the practicality as a container is not sufficient, for example, the storage amount is small, so this angle should be in the range of 40 degrees to 85 degrees. The range of 45 degrees to 80 degrees is more preferable. On the other hand, if this angle exceeds 85 degrees, the side wall becomes nearly vertical, and when the opening 7 is covered with a wrap film, the side wall falls down due to the tension of the wrap film, making it difficult to restore. There is a risk that the container will be loosened and the outer shape of the container may be easily deformed.

  In the wrapping packaging container 1 of this embodiment, the ratio W / Z of the length W of the long side wall 3A and the length Z of the short side wall 3B is preferably 1.05 or more, and 1.20. More preferably. If this ratio W / Z is less than 1.05 (that is, close to a square), the effect of preventing wrinkle / dent depression of the wrap film by the convex part 4 for preventing wrap depression formed on the long side wall 3A becomes insufficient. In addition, after the wrap film is stretched, the center of the opening 7 is easily depressed, and wrinkles are easily generated in the vicinity of the upper edge 5 and the like.

The wrap film is usually stretched with tension so as not to cause wrinkles and dents as much as possible. Since the wrap film is thin and easy to stretch, when tension is applied to the film in a direction parallel to the long side wall 3A, the vicinity along the side wall parallel to the tension direction is supported by the side wall, and this extension is maintained. However, since the distant portion is shrunk due to the tension to form a dent, the adjusted height cannot be maintained, and a dent is generated.
The wrapping wrapping container 1 of the present embodiment is provided with the wrap dent prevention convex part 4 in which the long side wall 3A is higher than the short side wall 3B and bulges into a gentle curve, so that the dent is formed. Almost no longer occurs. When this is reversed, that is, when the convex portion 4 for preventing wrap depression is provided on the short side wall 3B and the long side wall 3A is lowered, a depression is generated near the center of the wrap film stretched on the opening 7. End up.

  In the wrapping packaging container 1 of the present embodiment, the shape of the convex portion 4 for preventing wrap depression formed on the long side wall 3A is such that the curve formed by the upper edge 5 of the long side wall 3A is arcuate in side view. It is preferable to form such that When the shape of the convex portion 4 for preventing wrap depression is an arc shape, the container can be easily designed. In addition, after the wrap film first comes into contact with the top of the arc, the contact proceeds while the wrap film is spread on the same principle as the expander roll, so that the wrap film can be stretched on the opening 7 without any wrinkles. .

In the wrapping packaging container 1 of the present embodiment, the entire circumference of the upper edge 5 of the side walls 3A, 3B is on a two-dimensional curved surface obtained by curving the flat surface upwardly into a convex line, or the two-dimensional curved surface. And preferably on a continuous plane. If the entire circumference of the upper edge 5 of the side walls 3A and 3B is on this curved surface, the wrap film can be extended along the opening 7 without being forced to be stretched or twisted, and the stretched film. Indentation is unlikely to occur on the surface.
Whether or not the opening of the container satisfies this requirement is determined by painting the upper surface of the opening of the container and the outside near the upper surface, placing the container opening downward on a flat sheet of paper, and opening the paper evenly. When the ink is lightly pressed while being tilted in each direction so that it can come into contact with the ink and the ink around the opening is transferred without interruption, it can be determined that the opening of the container satisfies the above requirements.

  In the wrapping packaging container 1 of the present embodiment, it is preferable that the highest position of the upper edge 5 of the one long side wall 3A and the other long side wall 3A is in a position facing each other. By aligning the highest position of the upper edge 5 of the long side wall 3A, the wrap film can be easily stretched and can be wrapped without causing wrinkles or dents.

  The container 1 for wrapping packaging of this embodiment is formed so that the long side wall 3A is gently curved outward from both ends toward the center in the planar shape of the opening 7. By gently curving the side wall 3A outward, it is possible to prevent the wrap film from slackening, wrinkling, and depression due to the side wall 3A deforming inward against the tension of the wrap film. Note that not only the long side wall 3A but also the short side wall 3B may be formed to be gently curved outward.

  In the wrapping packaging container 1 of the present embodiment, the upper edge 5 of the short side wall 3B is substantially linear in a side view. If the upper edge of the short side wall 3B is a curved line that is convex upward in a side view, there is a risk of forming a recess in the corner. Moreover, if it is a downwardly convex curve, a dent tends to occur at the center.

  In the wrapping packaging container 1 of the present embodiment, the upper edge 5 of the long side wall 3A on the front side (lower side in FIG. 1A) is the long side on the rear side (upper side in FIG. 1A). It is formed lower than the upper edge 5 of the side wall 3A, and the opening 7 is inclined forward. Thus, by tilting the opening 7 forward, it becomes easier to see the package. Moreover, a bulky article to be packaged can be arranged on the rear side, and three-dimensional arrangement is possible.

In the wrapping packaging container 1 of the present embodiment, among the dimensions of each part shown in FIG. 4, the bulging height Bmm of the wrap dent prevention convex part 4 and the length Amm of the upper edge 5 of the long side wall 3A The ratio C (where C = B / A) is preferably in the range of 1/7 to 1/100.
The ratio C is set to 1/7 to 1/100 (at this time, in a typical example 8 of an embodiment described later, the bulging height B of the convex portion for preventing wrap depression when the ratio is changed is about 30 mm. (Corresponding to ˜2 mm), preferably the ratio C is 1/20 to 1/60 (in this case, in Example 8 of the embodiment described later, the bulging height of the convex portion for preventing wrap depression when this ratio is changed) B corresponds to about 11 mm to 3.5 mm).
Incidentally, the ratio C in the typical example 8 of the embodiment is 1/42, and the bulging height B of the convex portion for preventing wrap depression is 5 mm.

If the ratio C is smaller than the above range (C <1/100), the opening 7 is not significantly different from the planar opening of the conventional container (see the container 20 in FIG. 5), and the effect aimed by the present invention cannot be obtained. .
The ratio C does not need to be increased beyond the above range (C> 1/7) in order to achieve the object of the present invention. If the ratio C is too large, the height difference of the opening 7 becomes too large, creating a useless space in the container 1 and making the packaged article difficult to see, and the appearance is poor.
The ratio C may be increased at the front long side wall 3A and may be decreased at the rear long side wall 3A. However, if the difference is increased too much, the dent may be increased when the wrap film is applied.

In the wrapping packaging container 1 of the present embodiment, among the dimensions of the respective parts shown in FIG. 4, the ratio between the radius of curvature rmm of the wrap dent prevention convex part 4 and the length Amm of the upper edge 5 of the long side wall 3A. D (where D = r / A) is preferably in the range of 13 to 0.95.
The ratio D is in the range of 13 to 0.95 (at this time, in a typical example 8 of an embodiment to be described later, the bulging height B of the convex portion 4 for preventing wrap depression when the ratio is changed is about 2 mm. (Corresponding to ˜30 mm), preferably in the range of 8 to 2.5 (at this time, in Example 8 of the embodiment described later, the bulging height B of the convex portion 4 for preventing wrap depression when this ratio is changed) Corresponds to about 3.5 mm to 11 mm).
Incidentally, the ratio D in Example 8 of the embodiment is 5.4, and the bulging height B of the wrap dent prevention convex portion 4 is 5 mm.
When the ratio D is larger than the above range (D> 13), the opening 7 is not greatly different from the conventional planar opening, and the effect aimed by the present invention cannot be obtained.
This ratio D need not be smaller than the above range (D <0.95) in order to achieve the object of the present invention. If the ratio D is too small, the height difference of the opening 7 becomes too large, creating a useless space in the container 1 and making the packaged article difficult to see and poor in appearance.

FIG. 3 is a perspective view showing an embodiment of a food package according to the present invention.
The food packaging body 11 of the present embodiment has a configuration in which the food 10 as the package is put in the wrapping packaging container 1 described above and the wrapping film 9 is hung on the opening 7 of the wrapping packaging container 1 for packaging. It has become.

  The wrap film 9 used for the packaging can be appropriately selected from various commercially available products conventionally used in wrapping packaging for foods and the like. Particularly preferred wrap films include polyethylene-based resin and polyvinyl chloride-based resin wrap films.

  The food 10 in the wrapping packaging container 1 is not particularly limited, and examples thereof include various foods such as sashimi, meat, semi-cooked food (prepared food), and cooked food. The food 10 to be packaged is not limited to one type, and other types of food can be combined and arranged. For example, when sashimi is packaged as food 10, firstly, sashimi is put in a container, several kinds of fish sashimi, perilla etc. are placed on it, wasabi etc. in a small bag, and then a wrap film in opening 7 It is possible to take a packaging form such that 9 is used for packaging. Since a large number of small protrusions 8 are provided on the inner surface side of the bottom plate portion 2 of the wrapping packaging container 1, even if moisture or drip drips from the food 10, the small protrusions 8 and the inner surface of the bottom plate portion 2. The liquid accumulates in the gap between the food 10 and the food 10 is unlikely to look bad or become watery due to excess water.

  In order to stretch the wrap film 9 on the opening 7 of the wrapping packaging container 1, the manufacturer can also perform it manually, but it is preferable to use various commercially available wrap wrapping machines. When the wrap film is stretched, it is preferable that the wrap film 9 is stretched at a film elongation of 105 to 150%. If the film elongation is less than the above range, wrinkles and depressions are likely to occur in the wrap film 9. If the film elongation exceeds the above range, the side walls 3A and 3B are deformed inward to deteriorate the appearance of the container, and the wrap film 9 is easily broken, which is not preferable.

Here, as for the elongation rate of the wrap film 9, a predetermined range is marked in advance, the length of the predetermined range of the wrap film 9 before being stretched is measured, and then a predetermined tension is applied to the wrap film 9. A wrap film 9 was stretched over the opening 7 of the wrapping packaging container 1, the length of the predetermined range at that time was measured, and the film elongation (%) was determined by the following formula.
Film elongation rate (%) = predetermined length of wrap film 9 after pulling / predetermined length of wrap film 9 before pulling × 100

Can do.
In the food packaging body 11 of this embodiment, the stretched wrap film 9 follows the upper edge 5 of the opening 7 without difficulty. Therefore, it is possible to wrap without dents or wrinkles only by applying a slight extension to the extent that the wrap film 9 is loosened, and wrap wrapping becomes easy.
In the food packaging body 11 of the present embodiment, the inside of the opening 7 of the stretched wrap film 9 is hardly recessed. Therefore, even if the side walls 3A and 3B are not made excessively high, there is no fear that the package is in contact with the film, and a clean feeling and a high-class feeling can be improved.
In the food packaging body 11 of the present embodiment, the height of the side wall decreases as it goes from the long side wall 3A to the short side wall 3B of the container 1, and the packaged article can be seen well from the outside. In particular, the upper edge 5 of the front long side wall 3A is formed lower than the upper edge 5 of the rear long side wall 3A, and the opening 7 is inclined toward the front long side wall 3A. By setting it as a structure, a to-be-packaged item becomes easier to see.
In the food packaging body 11 of the present embodiment, since the container 1 has a structure in which at least the long side wall 3A is gently curved outward in the planar shape of the opening 7, the side wall is formed by the wrap film 9 covered in an expanded state. Since it can oppose the force which makes 3A and 3B bend inside a container, the wrap film 9 becomes difficult to loosen, and the state where the wrap film 9 was stretched with a pin without being depressed or wrinkled at the time of display is maintained for a long time Can look good and can improve cleanliness and luxury.
In addition, the food packaging body 11 of the present embodiment has a wrap film 9 that has a curved surface that is convex upward, and is in a tensioned state. Therefore, when a large number of food packaging bodies 11 are displayed side by side, Has the effect of feeling bright.
Furthermore, if the curved line formed by the upper edge 5 of the long side wall 3A is arcuate when viewed from the side, the container 1 can be easily designed, and the appearance of the container 1 can be improved naturally.
